slknow, that piece is the Brabus add-on lip for SLK. Check out the Brabus site and you will notice that this is the same piece on their cars. Unless, of course, somebody else manufactures a similar looking part for cheaper; and, I can safely say it will not be cheap. Yet, I want one too. I just haven't got around to replacing body panels yet - still working on upgrading my headunit to Alpine with iPod [

]. Man, I love technology!
p.s. Brabus really needs to get with the times and update some more decent pictures on its website. Methinks they spend too much time in the garage and do not come out for air often enough, they are going soft in the noggin. Some larger images aren't too much to ask, especially with all that auto customization going on over there . . .
